    Area of Science:

    • Biomedical Engineering
    • Vascular Surgery
    • Materials Science

    Background:

    • Arterial intimal flaps can compromise blood flow.
    • Securely reattaching these flaps is crucial for vascular repair.
    • Current methods may have limitations in strength or biocompatibility.

    Purpose of the Study:

    • To design and evaluate a bipolar electrocoagulating device for tacking arterial intimal flaps.
    • To assess the mechanical properties and biocompatibility of the thermal tack points.

    Main Methods:

    • A bipolar electrocoagulating device was developed.
    • The device was tested on rabbit descending aorta intimal flaps.
    • Vascular segments were analyzed for patency.
    • Tack points were examined using scanning electron microscopy.

    Main Results:

    • The device successfully thermally tacked intimal flaps to the artery wall.
    • Scanning electron microscopy confirmed sufficient tensile strength at tack points.
    • Minimal thrombogenicity was observed at the tack points.

    Conclusions:

    • The bipolar electrocoagulating device provides a viable method for securing arterial intimal flaps.
    • The tack points demonstrate adequate strength and biocompatibility for vascular applications.
